+Notes:
+
+While opentelemetry-cpp Logs are still in experimental stage,
+[#1383](https://github.com/open-telemetry/opentelemetry-cpp/pull/1383) updated
+opentelemetry-proto to 0.17.0, which includes some breaking change in the
+protocol, like
+[this](https://github.com/open-telemetry/opentelemetry-proto/pull/373). This
+makes `name` parameter for our log API unnecessary. However, this parameter is
+marked deprecated instead of being removed in this release, and it will be
+removed in future release.

-* [1]: The development of the metrics API and SDK based on new stable
-      specification is ongoing. The timelines would be available in release
-      milestone. The earlier implementation (based on old specification) can be
-      included in build by setting `ENABLE_METRICS_PREVIEW` preprocessor macro,
-      and is included under `*/_metrics/*` directory. This would be eventually
-      removed once the ongoing implemetation is stable.
